Tramlines Festival was created in 2009.
Because they look like tram/rail tracks.
In doubles tennis, players must stand behind the baseline when serving and cannot stand on or in the tramlines. The tramlines are part of the court boundaries for doubles play, and the server must ensure their feet are behind the baseline until the ball is struck. Standing on or in the tramlines during the serve would result in a fault.
It's out
In singles tennis, tramlines (the areas outside the singles sidelines) are considered out of bounds. This means that any ball that lands in the tramlines is not in play and does not count as a valid shot. Only the area between the singles sidelines and the baseline is used for scoring in singles matches.
The Festival was created in 1925-01.
the side tramlines are out, the back tramlines are in.
